Oil change at 20k, and found this in my catch can

[Meanrat75]

Had my oil change today by my local Ford dealership and was in the process of dumping my catch can like I normally do after each oil change. Once I got the can loose I was greeted by this:

This if the first time I have seen the residue this much and this creamed coffee look. Most times it's very minimal and still relatively black. Wondering if any of you guys have seen this before and if I should be worried about what was left in the can. First time I have had a turbo engine much less having to maintain a catch can. Thanks all!

Edit: this is the Mishimoto catch can for the 2.3L.

Looks like water contamination.

Looks like water contamination.

Agreed. In the winter you will sometimes see condensation water in a catch can. The first quick check to make is see if your oil in the pan exhibits the same water contamination or heaven forbid in your radiator.

Dang. I've seen a number of posts in the forum, people showing they don't find much if anything in their catch cans. Now you show this yikes. I might have to get me a catch can!

Water(Condensation) mixed with Oil Blowby (EGR/Recirc). Pretty standard for winter.

I often accumulate moisture to the point of emptying the can half way between OCI’s.

As long as you regularly run your rig to full operating temps(trips longer than 30 minutes), you’ll naturally burn off accumulated moisture and fuel that dilutes the Engine Oil.

That looks like the result of a lot of short trips. We used to be able to tell if a customer drove short trips as soon as we removed the oil fill cap. The underside would be milky sludge….might want to look at yours

Just emptied mine today while changing the oil and it looked the exact same. Just the catch can doing its job.

Thanks all, we have just gotten through all that snow and crap so that may have contributed to the mess. Just kinda shocked me.

Almost 4 ounces I got from mine early last year, it's definitely worse in cold weather. There really isn't much collected in the warm months. This reminds me to give mine a check.

You guys change your oil?

 

[Swacer]

Its water, due to condensation inside the head. Pretty normal in areas that see snow.

Short trip driving in winter condensation. It’s good to try to drive far enough to get to full operating temperature at least once a day to dry the condensation out. If your oil fill cap doesn’t the same way you’re probably fine. If it looks that way you need to drive further, take the long way home from work.

Seen the same in my 2.3l. 2.7 has much less in it. I run 93 most of the time and not even sure that has an effect (clearly, I'm not a mechanic). I live in the Midwest.

If anyone is interested I have the Mishimoto catch can set up for the 2.7 available...complete with very low miles. Even with just under 2,000 mi I got oil out of both cans. I sold my Bronco, and hastily took the parts off that I knew weren't going to get me any extra money during the sale. I initially wanted only one can, but then when I realized they released both cans I had the additional parts shipped to me after I paid the difference so I have everything including everything for either a single or dual can setup. I live in Thousand Oaks and I prefer local pickup... I have them listed in the for sale section for 175.

Fuel octane won’t affect crankcase condensation. It’s strictly a cold weather/short trip condition.
